Hydrothermal synthesis, characterization and luminescent properties of GdPO4·H2O:Tb3+ nanorods and nanobundles

Synthesis and photoluminescent properties of cuboid-like Y2(C2O4)3:Tb3+ green-emitting phosphors

“…4c and d, the average length of particles are more larger than 5 lm. It may be the reason that pH value increasing can promote the growth of the particles [20,21]. When the pH value increasing, the H + concentration decreasing, so the C 2 O 4 2À concentration increasing leads to crystal growth rapidly and particle aggregation.…”

“…The other bands present in the FT‐IR spectrum of GdPO 4 belonged to the phosphate groups. The split bands at 1077, 1007, and 967 cm −1 in the GdPO 4 spectrum were characteristic of the monoclinic GdPO 4 phase (phosphate PO stretching) . The vibration spectra gave a conclusive evidence of the GdPO 4 monoclinic‐phase formation …”

“…The absorption bands at 1404 cm −1 belonged to the CH 2 scissor bending vibration because of the presence of residual ethanol . Bands around 1617 and 3500 cm −1 were ascribed to hydration water (OH bond) in the as‐prepared powders of both the two compounds . The spectrum of GdPO 4 showed weaker absorptions at 1617 and 3500 cm −1 due to the removal of hydration water after calcination, compared with GdPO 4 ·H 2 O.…”

“…The bands located at 551 and 629 cm −1 are attributed to O–P–O bending vibrations. The band centred at 825 cm −1 is due to V–O stretching, whereas the bands located at 1638 and 3452 cm −1 are assigned to the H–O–H stretching vibrations probably due to the intrinsic hygroscopic nature of our materials.…”
